Cecil Beaton - who can sell him

Im doing some research on Cecil Beaton. after a quite long time with telephone calls to agencies and internet search, i cant find out who licence or own the copyrights for the famous Beaton picture with women in Charles James clothing. Ref:http://bridesmagazine.files.wordpres...beaton1948.jpg

This is info i need for an article im writing on. I have spotted the image used in commercial ads, and will try to investigate if one of the fashion world/ Vogue-universe most famous pictures, are stolen and used illegal.
